More heat, more smoke, more fruitiness…when red.
Scoville heat units (SHU): 2,500 – 10,000
Jalapeño reference point: Equal heat (with the chance of slightly hotter)
It looks like a jalapeño and even tastes like a jalapeño, but the Fresno pepper has a few tricks up its sleeve that make it a very popular chili in its own right. It delivers a slightly spicier kick, like a mild serrano chili, and in its mature red form, the Fresno pepper has a fruitier, smokier taste. This is a favorite for foodies looking for a twist on the norm.
So how do you tell the difference between a jalapeño and a Fresno pepper?
Not easily. These two chilies are in fact often confused for each other. They both share similar size traits – two to three inches long, slightly curved, and smooth skin. They both mature from green to a fiery red. As green chilies, they even share very similar tastes. It’s easy to see why even supermarkets mislabel Fresno peppers as jalapeños.
Where the difference lie are the thickness of the walls, the taste as a mature red chili, and the overall heat:
- Fresno peppers have thinner walls which make them more conducive to drying. They can be stuffed, but the jalapeño, with its thicker walls is better for that use case.
- The Fresno gains a smokier, fruitier taste than a jalapeño as it matures to its red hue. Many, in fact, prefer the more complex flavors of the Fresno over the jalapeño, especially those that love to experiment in the kitchen.
- Both peppers have a similar heat level, but the Fresno kicks it up a notch as it ages.
How hot are we talking? How hot is a Fresno pepper?
On the Scoville scale, the Fresno chili ranges from 2,500 to 10,000 Scoville heat units. That again closely mirrors the jalapeño, but it can range closer to a mild serrano pepper in overall heat in its mature red form. Overall: this is a heat level that’s very kitchen-friendly, on the milder side of medium compared to other chilies.
Where did the name come from?
Fresno chilies were first cultivated in 1952 by Clarence Brown Hamlin, and he named the chili after Fresno, California. The Fresno is still widely grown in California.
What can you make with Fresno peppers?
Let’s first say that any recipe that calls for a jalapeño or serrano pepper is fair game for a Fresno pepper. They are terrific in salsas, hot sauces, and ceviche, and they stuff decently well too. Pickled Fresno chilies are loved by many, and cutting them fresh into rings for sandwiches and burgers (like the jalapeño) is very popular too.
The more complex flavors of the red Fresno compared to the jalapeño has made this a chili loved by foodies and gourmet restaurants. It’s a chili that’s ripe for culinary experimentation.
Where can you buy Fresno chilies?
You can find them fresh in supermarkets and farmer’s markets, especially on the west coast of the United States. They can be mislabeled as jalapeños, and, as mentioned, it’s tough to tell the difference when standing in the store. Online it’s easy to find Fresno pepper seeds and red Fresno hot sauces, among other jarred and bottled Fresno-based condiments.
The Fresno pepper may not be as widely available as the jalapeño, but if you do come across them in their mature red form, it’s well worth giving them a try. You may enjoy the uptick in spice and fruitier flavor. In fact, if you’re like many, it may be hard to go back to the jalapeño as your kitchen staple chili once you’ve tried the Fresno.
